BMW PERFORMANCE 
The Heart Of Every 4 Series
440i: Generating 320 hp and 330 lb-ft. of torque from 1380-5000 rpms, this advanced inline six is a powerful turbocharged engine. Turbo lag has been virtually eliminated, thanks to Double-VANOS steplessly variable valve timing, direct fuel injection, and BMW's inspired use of the latest TwinPower Turbo technology.
Inhale
At higher speeds, Air Curtains below the kidney grille redirect airflow around the outside of the front wheels, improving efficiency and boosting performance.
Aggressive Performance
Made possible by four driving modes, including ECO PRO and SPORT+. In addition, Driving Dynamics Control adds an increased stability even at high speeds, so all that jaw-dropping power comes at no cost to safety.
Track Handling Package
Designed specifically for the serious sport driver, the Track Handling Package raises the already agile handling with Variable Sport Steering and Adaptive M Suspension. Greater braking performance with the M Sport Brake takes potent stopping power to the next level.

Focus On The Road
Eight sensors — four in the front, four in the rear — help you judge how close you are to other vehicles and unseen objects when parking. And in coordination with Rear View, Park Distance Control lets you know if your vehicle can fit in a space before you begin backing in.
